Impairments on the Construction of a Cosmic Neutrino Detector in a Romanian Salt Mine
Natural Sciences, EarlyView.The modulus of the transfer function of an antenna when boreholed in salt. With red are represented results from the Targu Ocna salt mine and with black‐from Slanic salt mine ABSTRACT Indirect cosmic neutrino detectors utilize dense media to enhance the likelihood of neutrino interactions within the detection volume.

High energy gamma ray astronomy [PDF]
High energy gamma ray astronomy has evolved with the space age. Nonexistent twenty-five years ago, there is now a general sketch of the gamma ray sky which should develop into a detailed picture with the results expected to be forthcoming over the next ...

Structure and Migration Mechanisms of Oxygen Interstitial Defects in β‐Ga2O3
physica status solidi (b), EarlyView.The structures and diffusion mechanisms of interstitial oxygen in different charge states in β‐Ga2O3 are extensively studied using density functional theory. The results provide a detailed map of the potential energy surface for oxygen interstitials in β‐Ga2O3 and demonstrate how these ions migrate between different rings in the structure.

Gamma Ray Astronomy with Magnetized Zevatrons
, 2005 Nearby sources of cosmic rays up to a ZeV(=10^21 eV) could be observed with a multi-messenger approach including secondary gamma-rays and neutrinos. If cosmic rays above ~10^18 eV are produced in magnetized environments such as galaxy clusters, the flux ...

\gamma-rays from starburst galaxies
, 2012 In this paper the current status of \gamma-ray observations of starburst galaxies from hundreds of MeV up to TeV energies with space-based instruments and ground-based Imaging Atmospheric Cherenkov Telescopes (IACTs) is summarised.

Investigation of Transport in OECTs with Electrochemical Strain Wave Microscopy
Small, EarlyView.Electrochemical strain waves (ESWs) are generated in mixed conductors by alternating charge injection at a contacting electrode. They propagate into the device channel through combined charge transport and swelling. AFM experiments map the local amplitude and phase of ESWs in organic electrochemical transistors (OECTs), providing quantitative insight ...

Ground-based very high energy gamma ray astronomy: Observational highlights [PDF]
It is now more than 20 years since the first ground based gamma ray experiments involving atmospheric Cerenkov radiation were undertaken. The present highlights in observational ground-based very high energy (VHE) gamma ray astronomy and the optimism ...
